| titleOfInvention | Process for the preparation of new 3-aza-A-homosteroids |
| abstract | Analgesic and CNS active 19-hydroxy-3-aaza-a-homosteroids. M3A. are new cmpds. of formula: opt. containing a double bond at 4a, 5 or 5,6 (R' = H, lower alkanoyl; R2C = OH opt. esterified or etherified; R3 = free or ketalised oxo group; OH opt. esterified or etherified where R4 is H, or lower aliphatic hydrocarbon e.g. alkyl; or opt. esterified or etherified where R5 is acetyl or hydroxyacetyl; Also disclosed is a process for preparing cpds. of formula: (opt. containing a double bond at 4,4a or 5,6 and where R1, R3 and R3 are as in I) by treating a cpd. of formula (where one of R0 is oxo and the other represent 2 H atoms and R2 is as above but not free oxo) with hydroxylamine followed by Beckmann rearrangement of the oxine. Optionally conversion of various groups subsequently, e.g. formation of salts, hydrolysis etc. |
